Application filed iOctober 25, 1917.

To all whom t may concern:

Bc it known that l, LAWRENCE H. STOWELL, a citizen of the United States, residing at l'litchville, in the county of Barnes and State of North Dakota, have invented certain new and useful improvements in ISnowplows, of

which the following is a specification.

yprovide a This invention relates to snow plows.

One of the objects of the invention is to snow plow of such improved construction that it will cut its way through snow which has become very solidly packed and through snow which has a hard crust formed thereon.

Another object of the invention is to provide a device of this character which thoroughly cleans the path over which it is to travel, so to render its operation complete and thoroughly effective.

A further object of the invention is to provide a device of this character which will eut through very deep snow and eiectively remove the snow from'the channels cut thereby.

.another object is to provide a device of this character which is so simple of construction as to he manufactured at a comparatively low cost, and which may be operated entirely from a single source of power such as an engine or motor which is movable along the track which is heilig cleared of snow.

Other objects and advantages may become apparent to persons who read the following details of description in connection with the accompanying drawings in which,-

Figure 1 is a side elevation of one form of embodiment of my invention.

Fig. 2 is a top plan view thereof with blades -ll in section.

Fig. 3 is an enlarged detailed perspective view showing the peculiar construction of the combined excavating and conveying device. Fig. 4; is a transverse sectional view through the convever frame.

Referring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views. the device is represented as being` in position on a railroad track, and is therefore provided with flanged wheels 5 which support the main body portion or frame 6. An engine or motor 7 of conventional form, is connected by a belt 8 to a pulley 9 and a main shaft 10. The main shaft is provided with gear wheels 11 one Specification of Letters Patent.

of which is secured on each end of the main shaft and meshes with the gear wheel 12. As there are two of the gear wheels 12 each of which comprises an element of the train of gearing on one side of the machine, which is identical in construction and arrangement with a similar train or gearing on the opposite side of the machine, only one of these trains of gearing will be described in detail. In considering one of these trains of gearing, it will be seen that the gear wheel 12 is connected to a gear wheel 13 through the medium of a shaft 14 which is journaled in suitable bearings 15. The gear wheel 13 meshes with a similar gear wheel 16 which is secured to the inclined shaft 17 for driving the latter. The shaft 17 is rotatable in suitable bearings 18 and carries a worm 19 on each of its ends.

The combined excavator and conveyer consists of a frame 20 which carries bearings 1S, and which also carries bearings for the upper and lower shafts 21. These shafts have worm wheels 22 secured on their opposite ends, and these worm wheels mesh with the worms 19, respectively. Upon each shaft 21 is mounted a hexagonal or prismatic rotor 23, the plane surfaces 24 of which comprise seats on which the plane surfaces 25 of plates or links 26 rest during operation of the machine. Certain of the plates 26 carry plates 27 the cutting edges 28 of which are spaced from the plates 26 by means of triangular plates 29. Although I may provide each of the plates 26 with the elements 27 and 29, this embodiment of my invention only discloses alternate ones of the plates 26 provided with these elements, and the elements 26, 27 and 29 combine to form a bucket between adjacent plates 27 which are not provided with the elements 27 and 29. Each bucket is connected with the adjacent plate 26 by means of a hinge 30 which is continuous from side to side of the conveyer chain which is formed by the alternate plates and buckets.

The excavator and conveyer frame is inclined upward and rearward so that the lowermost ones of the plates 27 are the first to come into contact with the snow to be excavated. However, in case the snow is very deep and has a crust thereon, the upper or intermediate ones of the plates engage with this crust so as to lift it and break it into such pieces that may be carried up in the buckets.

In order that the snow may be disposed after being excavated and elevated, l provide a platform 3l onto which the snow is deposited by the buckets, and l provide a blower oic ordinary construction, having` nozzles 82 through which a current of air passes into contact with tee snow oiithe platform 3l and in the buclrets, so as to blow the snow laterally from the platform and buckets past the channel from which the snow has been taken. The blower may comprise a fan wheel 33, a. shaft Bil and a pulley 35.

In order that the blower may be operated simultaneously with the operation or" the excavator and conveyer, l provide a gez r wheel 36 in Vmesh with a gear wheel 37 on the shaft l0. rThe gear wheel 36 is carried by a shaft 38 which also carries a pulley 39. T he pulleys 85 and 39 are connected by the belt 40.

It will be seen, therefore, that when the shaiit l0 is rotated by the engine, this shaft not only drives the countershatt l-l, but also Vdrives the counter shaft 34, thereby driving the combined excavator and conveyer simultaneously with the operation ot the blower.

The machine may be driven forward by means of the engine 7 or by external means.

In order that the trains oi gearing may be protected from contact with the sides oi' the channel being made through the snow, and to provide sufficient clearance 'for the traclz wheels 5, l provide upwardly and outwardly inclined blades 4l. it will be seen that these blades cut the snow vertically and draw the *same inwardly into the buckets ot the conibined excavator and elevator.

ln Fig. 2 oi' the drawings, the blades 41 are shown in section, thereby eliminating the shaft 10 and secured against rotation with relation to the shaitt l0. Any appropriate si tting means, of which the collar 44 is an element, may be employed tor shitting the sleeve l2 so as to move the gear wheel 3T out ot mesh with the wheel 36 and to move the gear wheel 43 into mesh therewith.

, T v 'l ,f l i Although l have oesciibeu this machine iii minute detail, it is to be understood that iy invention is not limited to these exact details et construction and arrangement of parts, but my invention is susceptible of such changes that do not constitute a departure from the inventive idea pointed out in the appended claim.

What l claim as my invention is:

A snow plow, comprising a wheel supported body having its forward portion extending vertically aiid terminating in an elevated platform, and liavi-ng its front side inclined upwardly and rearwardly, an endless excavator mounted on the inclined tace ol the body and adapted to deliver the snow upon the elevated platform, a tan blower and nozzles connected with the tan blower and disposed to deliver blasts of air laterally across the nlatiiorm to discharge the snow l C tl refr-oni the sides ot the machine.

in testimonyv whereof l aliix my signature in prese` te or two witnesses.
